Research on High Voltage Power Frequency Electric Field Intensity in High Voltage Instrument and Equipment Measurement

High-voltage instruments and equipment in the use of the process will produce high-voltage industrial frequency electric field risks to human health, and measurement personnel in the measurement of such instruments and equipment often need to be close, long exposure to high-voltage industrial frequency electric field. This paper selected a high-voltage test transformer as the object to be tested. By constructing an analysis model and formulating a detailed test plan, a high-precision field strength meter was used to determine the power frequency electric field strength of the test transformer in the measurement process, Combined with related national standards and mathematical models, this paper proposed a variety of suppression and shielding schemes, compared the effects of different schemes through experiments, and proposed relevant measurement safety protection suggestions.
